To get an idea of exactly how small the worldâs smallest insect is, take out a ruler and look at those tiny lines that appear in between centimeters (make sure youâre not on the side that measures in inches). If in doubt, ask a grown-up to help you find the millimeters.
Nausea and vomiting are very nonspecific symptoms that can be common among people with stomach cancer. Persistent nausea and/or vomiting needs to be checked by your doctor. It can indicate a serious health problem and can cause damage to the lining of your esophagus.
Vomiting (throwing up) and diarrhea (frequent, watery bowel movements) can be harmful because they can cause dehydration. Dehydration occurs when you lose too much fluid. Vomiting and diarrhea can be caused by a number of things, including viruses, bacteria, parasites, certain medicines, or certain medical conditions. Foods that are hard to digest (such as too many sweets) and undercooked (raw or partially raw) meat or fish can also cause vomiting and diarrhea.
